I broke in the Saito 1.00 twin in the last hour, I did my usual 10 minutes at various rpm. During the 5,000 rpm run the engine picked up 450 rpm
10 minutes @=====4,000
10 minutes @=====5,000
10 minutes @=====6,000
9.5 minutes @==== 7,000, 16oz tank went empty, I shut it down rather than let it go lean and quit.
5 more minutes @ 7,500, then set HS needles for 9,450 peak, then set airbleds for sub 2,000 rpm idle.
Fuel===WildCat 15% Premium Extra
Plugs===Pre H9 Super plug
Prop===Bolly 13.5x8, a surprise as I exected 8,200 or 8,300 at most, a pleasant surprise.

Those are some good figures. That engine would do well on a 60 size stick

How does that compare with your 90TS

Jim, if memory serves, the TS 90 turned an APC 14x6 at 9,400, I'll see if I can dig it up before I say it Gospel.

Woops, I found it. Well, so much for the memory.

Hobbsy,

Nice engine! Let me know when you need some TurboHeaders for it. By the way, the new model 1.80 TurboHeader is available now.

Thanks Jim, I'll give you a holler, I've never owned a 1.80, I skipped from the 1.50 to a 2.20.

Hi mbrennan1,

I don't have the size, but I can find you the screws... They're Saito p/n 6514 (Horizon Hobby stock number SAI6514) and are pretty cheap...

Look here for them. http://www.horizonhobby.com/Products...ProdID=SAI6514

I hope this helps, just my $.02

Question for the gurus. I have a Saito 100 that has a 16x8 MAS on it and would like to try a 3 blade prop. Do I go 15x7 or 15x8 or 16x7 ?? Can't remember the rule of thumb for that. Thanks.

Definitely not a guru here but I do remember the rule of thumb. Going from two blade to three, you should drop 1" in either diameter or pitch, so 15x8 or 16x7 would conform with that general guideline. However, with that said, 16x8 seems like a lot of prop for a 1.00. My guess is that the 15x7 would be a better match for your engine. A tach will help you sort it out.

That's one of the most useful things I've read here at Club Saito. I never knew what to do after the first ten minutes at 4000rpm.

16 X 8 is a Saito 1.50 propeller, not a Saito 1.00

You need to step down to a 14 X 6, a 15 X 6, or a 15 X 8.

Try that before you go to a three-blade. I'll bet that thing is lugging like a bear. No RPMs at all, I'd bet.

As mentioned already, the Saito 100 normally uses two blade props in the 14 X 6, 14 X 8, and 15 X 6 range. For aThree blade prop, drop an inch in diameter. You would probably like a13 X 8 three blade best.

Hi,
I burned out the printed wiring on my power panel stalling my starter trying to start an engine, but direct wiring to the 12 volt battery turned the engine over to start with a little initial assist from a hand flip with the starter engaged. I think I need to upgrade my starter system for more torque.

Was this more powerful starter you used for the 180 a 12 volt starter running on 18 or 24 volts, an 18 or 24 volt starter designed for 18 or 24 volts, or a reduction drive starter? Can a 12 volt Sullivan starter be operated on 18 or 24 volts without burning out, or is it better to wire two 12 volt, 9 or 10 ampere hour batteries in parallel to provide more available currrent at the 12 volts?

Thanks for any inputs.

You can do it either way. The series connection resulting in more voltage gives you more speed

If you stall your starter you stand to weld the switch contacts together or possibly damage the armature

Most of our model starters can be used with up to 24 volts

Leed, that's the reason I came up with the this procedure, the Saito manual was so vague as to be useless. I came up with this so I'd have something I could easily keep rack of and it would be repeatable. After some 22 engines both mine and others it has worked every time. The manual says that a Saito is flyable after 40 minutes so I came as close to that as I could.

Hi! For my Saito 180 and FG-36 I'm using this starter with a small mods. http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFT88 I will place the pics tomorrow.

I actually have one of these on order which will arrive some this week. It is also the one I used yesterday and it worked perfectly. Does your 180 idle very smoothly or is it rough?

If you mean the size of the plane re the size of the engine you are right. Its a 70 inch wing span but I do not have to fly it at full throttle.

I'm trying to find a Prop Nut setup that locks on a Saito 150. My problem is that I have to try and make it work on a Waco, and the propeller takes up most of the shaft. Thinking of a Higley with a Higley Locker nut behind it. Also thought about using a Tru-Turn Part # TTN-0750-A-825 3/4" X 8 X 1.25

Here's a link to that one. Thought about using a Higley Locker Nut behind that maybe (?).

http://www.truturn.com/cgi-bin/store...exact_match=on

Any better setups around?

Jim
